Change in coreboot[master]: soc/amd/picasso: Drop the inclusion of entry16.ld and reset16.ld
by Furquan Shaikh (Code Review) 17 Nov '20

Furquan Shaikh has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/43281 ) Change subject: soc/amd/picasso: Drop the inclusion of entry16.ld and reset16.ld ...................................................................... soc/amd/picasso: Drop the inclusion of entry16.ld and reset16.ld This change drops the inclusion of entry16.ld and reset16.ld instead adds the content of those files directly in memlayout.ld in picasso. This is done to allow the work for top-aligning bootblock to happen independent of Picasso layout. Once that is complete, Picasso layout can be re-evaluated to see if it can make use of the common bootblock linker file includes. TEST=Verified that coreboot.rom generated using --timeless is the same with and without this change for trembyle.
